CALIBRATION PROCEDURE
PXIe-5185/5186
This document contains information for calibrating National Instruments PXIe-5185/5186
digitizers. The PXIe-5185/5186 digitizers were developed jointly between Tektronix and
National Instruments. The devices use Tektronix, Enabling Technology
™
to deliver wide analog
bandwidth and high-speed sampling on the National Instruments Synchronization and Memory
Core (SMC) technology with TClk synchronization.
